Abstract
An apparatus and method for using a multi-purpose tool having a handle with a shaft affixed thereto and a cylinder assembly disposed to longitudinally slide on the shaft between positions in which the shaft is fully extended or fully retracted. While in the fully retracted position, a cylinder having a plurality of chambers housing different tips may be rotated about its axis, which is offset from the shaft, until the desired tip aligns with and engages the shaft in coupling engagement. The shaft is then extended to its fully extended position, thus extending the tip and permitting free rotation of the working tip for use in performing work on a workpiece. Changing the tip requires retracting the shaft, rotating the cylinder to engage the next desired tip, and extending the shaft back to its fully extended position. The multi-purpose tool may be attached to a power tool for power driven rotation.
